Is there a way to move constrained objects and constraints to new locations?

I have an actor that will be using different vehicle models, and depending on the size and shape of the model, I need to move the components and constraints around to different locations. But I can’t seem to find a way to disable the constraints to move the constrained components around and then lock them in the new location. It seems like the constraints can’t be moved or reset to new locations at all. Does that mean I have to create an entirely new child blueprint for each conceivable vehicle model I end up using, or is there some way to do it?
